Contaminant Exposure and Transport from Three Potential Reuse Waters within a Single Watershed

Environmental Science & Technology, Год журнала: 2023, Номер 57(3), С. 1353 - 1365

Global demand for safe and sustainable water supplies necessitates a better understanding of contaminant exposures in potential reuse waters. In this study, we compared load contributions to surface from the discharge three waters (wastewater effluent, urban stormwater, agricultural runoff). Results document substantial varying organic-chemical contribution effluent discharges (e.g., disinfection byproducts [DBP], prescription pharmaceuticals, industrial/household chemicals), stormwater polycyclic aromatic hydrocarbons, pesticides, nonprescription pharmaceuticals), runoff pesticides). Excluding DBPs, episodic storm-event organic concentrations loads were comparable often exceeded those daily wastewater-effluent discharges. We also assessed if irrigation corn resulted measurable effects on rain-induced harvested feedstock. Overall, target-organic 491 g study field during 2019 growing season did not produce dissolved organic-contaminant subsequent events. Out 140 detected organics source irrigation, only imidacloprid estrone had that observable differences between effluent-irrigated nonirrigated fields. Analyses pharmaceuticals per-/polyfluoroalkyl substances at-harvest corn-plant samples two antibiotics, norfloxacin ciprofloxacin, at 36 70 ng/g, respectively, samples; no contaminants noneffluent irrigated samples.

Nonchemical Aquatic Weed Control Methods: Exploring the Efficacy of UV-C Radiation as a Novel Weed Control Tool

Plants, Год журнала: 2024, Номер 13(8), С. 1052 - 1052

Опубликована: Апрель 9, 2024

Aquatic weeds, including invasive species, are a worldwide problem. The presence of aquatic weeds poses several critical issues, such as hindering the continuous flow water in irrigation channels and preventing proper distribution adequate quantities. Therefore, effective control measures vital for agriculture numerous downstream industries. Numerous methods controlling have emerged over time, with herbicide application being widely used established method weed management, although it imposes significant environmental risks. is important to explore nonchemical alternative existing emerging potentially posing fewer hazards compared conventional chemical methods. In this review, we focus on methods, encompassing mechanical, physical, biological, other approaches. We primarily evaluated different discussed review based two main criteria: (1) efficiency alleviating problems location-specified scenarios (2) impacts environment, well potential health safety treatments UV-C-radiation-mediated method, which considered novel technique. Since there limited published literature available UV-C radiation exclusively control, our previous reports successfully terrestrial algal populations. order compare mechanisms involved reviewed respective pathways leading plant cell death, growth inhibition, diminishing reemergence justify use treatment habitats viable source control.

Factors contributing to pesticide contamination in riverine systems: The role of wastewater and landscape sources

Wastewater treatment plant (WWTP) discharges can be a source of organic contaminants, including pesticides, to rivers. An integrated model was developed for the Potomac River watershed (PRW) determine amount accumulated wastewater percentage streamflow (ACCWW) and calculate predicted environmental concentrations (PECs) 14 pesticides in non-tidal National Hydrography Dataset Plus Version 2.1 stream segments. Predicted were compared measured (MECs) from 32 sites that represented range ACCWW land use evaluate performance assess possible non-WWTP loading sources. Statistical agreement between PECs MECs strongest insecticides, followed by fungicides herbicides. Principal component analysis utilizing optical fluorescence ancillary water quality data identified urban runoff Pesticides indicated relatively larger sources WWTPs included dinotefuran, fipronil, carbendazim, thiabendazole, prometon whereas imidacloprid, azoxystrobin, propiconazole, tebuconazole, diuron more related runoff. In addition, generally comprised low proportion MECs, which indicates dominant beyond WWTP discharges. Cumulative potential toxicity higher with greater and/or located areas. Imidacloprid, carbendazim accounted largest portion across sites. The chronic aquatic life benchmarks freshwater invertebrates exceeded 82 % imidacloprid detections (n = 28) 47 fipronil 19). These results highlight ecological implications pesticide contamination also legacy effects soil groundwater Pesticide management strategies mitigate both current historical impacts may improve health ecosystems.

Causal inference approaches reveal both positive and negative unintended effects of agricultural and urban management practices on instream biological condition

Journal of Environmental Management, Год журнала: 2024, Номер 361, С. 121234 - 121234

Agricultural and urban management practices (MPs) are primarily designed implemented to reduce nutrient sediment concentrations in streams. However, there is growing interest determining if MPs produce any unintended positive effects, or co-benefits, instream biological habitat conditions. Identifying co-benefits challenging though because of confounding variables (i.e., those that affect both where applied stream biota), which can be accounted for novel causal inference approaches. Here, we used two approaches, propensity score matching (PSM) Bayesian network learning (BNL), identify potential MP the Chesapeake Bay watershed portion Maryland, USA. Specifically, examined how may modify conditions impact fish macroinvertebrate indices biotic integrity (IBI) functional taxonomic endpoints. We found evidence effects benthic macroinvertebrates indicated by higher IBI scores specific endpoints like number scraper taxa lithophilic spawning a subset regions. our results also suggest have negative especially on sensitive key water quality metrics conductivity.
